Wouldn't of these technically be roots and not prefixes? I'm a bit of a novice in etymology.

Using metric units isn't really fair because any metric prefix works with them

It's misleading because they use the USA spellings of metric, so it's a bit of an extra thinking process for non-Americans too.

Kept thinking "Diagon" for the __agon one... Taking too many Harry Potter quizes on here I think!

It didn't help that we spell deciliter "decilitre" here in Australia. Still managed 18 despite the Americocentric spelling.

Exactly the same here. Had to groan that I didn't think of litre being liter once I saw it.

I think the entire world outside of the USA spells it "litre", so this really should be changed for clarity.

"liter" doesn't really register and the rhythm of the word would be totally different for "deciliter"

?? I spell it litre, but I definitely pronounce it liter... Doesn't everyone?

It is an American website, what do you expect? Cut the guy some slack

Yeah, I agree Jon. It isn't really so hard to understand, is it?

liter/litre

meter/metre

The correct spelling is quadriceps. It's already singular, so taking the s off is just a misspelling.

Its wierd the may my brain can't unsee wrong answers - once it allocates Aca to demic and Lat to itude its really difficult to make it blank that out and restart.

maybe is it harder for english speaking people, but i found it easier (i'm frenchspeaking) probably because of the latin and greek roots

I really liked the quiz. There is just one thing that bugs me: The "-opus" vs. "-agon" clue is a bit misleading, as the prefix in that case is octo- or octa- and the rest of the word should be -pus or -gon.

Still, it is the most guessed...

Underbrush! I've learnt a new word. Disappointingly it turns out not to be the opposite of "over the brush"

In "The World According to Garp," one of the characters, a child, thinks that the undertow he is told to watch out for when swimming in the ocean is "The Undertoad," a frog of some sort that grabs hold of swimmers and pulls them to their doom. That's one of those images that, once you hear it, is hard to shake.
